Elite Dangerous would like to have a word with you...
There are others of various degrees of quality and gameplay focus as well, the X series, Avorion, Rebel Galaxy, everspace, etc.
This isn't a dying genre, but it is on the back burner for triple a developers as they are fad chasers. Which is why this game is ultimately hollow, it isn't a space flight sim so much as a multiplayer team death match/arena fighter, probably made in such a way to bolt on mods like battle royal.
You gotta dig into indie titles (and deal with indie issues) to get genre's off the beaten path.
